ABSTRACT:
Improved corrosion inhibitors for use with road deicing compositions are provided which lessen the typical corrosive properties on metal and/or concrete resulting from application of road deicers. The inhibitors of the invention include respective quantities of a citrate component such as citric acid, as well as a second silicate or metasilicate component, e.g., sodium metasilicate. The inhibitor compositions preferably include from about 0.5%-50% by weight of the citrate component and from about 50%-99.5% by weight of the second component. The inhibitors are generally used at a level of at least about 1.5% by weight to create inhibited road deicing mixtures.
